The furnace proposed has a cylindrical construction. It has a shell constructed in mild steel plates and reinforced with rolled members. It will have a lining of appropriate grades of low-density ceramic fibre blankets. A crucible [Crucible and stand] will be centrally located in the furnace. Heating element coils will be supported on ceramic bobbins and mounted vertically on the furnace walls. The furnace will have a manually operated Melt Cover to conserve heat.

A temperature sensor will sense the temperature inside the furnace. A continuous dipping thermocouple will sense the melt temperature. Two Temperature Indicator and Controllers mounted inside a control panel will control the furnace in the On/Off mode. The control panel also houses the MCB, contactors, ammeters, voltmeter with VSS, Energy Meter, indicating lamps, switches and other switchgear. All components used are industry-standard. We have made provisions to measure the melt temperature separately.
